How to send network requests in QWebEngine

Since QWebEngine does not interact with QNetworkAccessManager, is there any other way to send network requests and receive replies in QWebEngine?
For example, when WebKit was used, code looked like this

Qt WebEngine Core provides an API shared by Qt WebEngine and Qt WebEngine Widgets for handling URL requests issued for the networking stack of Chromium and for accessing its HTTP cookies.

Implementing the QWebEngineUrlRequestInterceptor interface and installing the interceptor on a profile enables intercepting, blocking, and modifying URL requests (QWebEngineUrlRequestInfo) before they reach the networking stack of Chromium.

A QWebEngineUrlSchemeHandler can be registered for a profile to add support for custom URL schemes. Requests for the scheme are then issued to QWebEngineUrlSchemeHandler::requestStarted() as QWebEngineUrlRequestJob objects.

The QWebEngineCookieStore class provides functions for accessing HTTP cookies of Chromium. The functions can be used to synchronize cookies with QNetworkAccessManager, as well as to set, delete, and intercept cookies during navigation.
